Patent DE-2313571-A1 (DE)
Title: Continuous bar extn. on continuous casting machines - at controlled speed using spring-loaded levers mounted on reciprocating slides
Inventor: MILJAJEW BORIS FEDOROWITSCH
IPC: B22D11/128
Filed: 1973-03-19
Abstract: A horizontal tube is fixed to a vacuum chamber holding the molten metal, and two circular slides are mounted on the outside dia. of the tube. Each slide has two nuts at 180 degrees which run on threaded spindles. A frame houses the two spindles which are driven by a worm gear which is reversible. Each spindle has a section of left-hand and right-hand thread, so that when it rotates in one direction, one of the slides moves a specific distance to the right while the second slide moves the same distance to the left. When the direction of spindle-rotation is reversed, the direction of the slides is reveresed, so a reciprocating motion is achieved. Each slide is fitted with four spring-loaded levers which project through slots in the horizontal tube so that they are set at a narrow angle to, and in contact with, the continuous cast bar. When one slide moves in the direction away from the vacuum chamber, the levers engage with the surface of the cast bar, propelling it at the desired spped. During this cycle, the other slide is moving in the reverse direction during which the levers slide along the cast bar, i.e. they only engage the bar when travelling in one direction. The device is gas-tight and can be used under vacuum or inert gas; it is mainly for melting electrodes for sec. melting in electro-slag furnaces, vacuum-arc- and induction furnaces.

Title: Aerated sand trap for sewage plant - using air-induced roll-over motion in annular channel
Inventor: POERSCH RUDOLF DIPL ING
IPC: B01D21/00
Filed: 1973-04-28
Abstract: An aerated sand trap for clarifying plant precipitates the sand entrained with the sewage by imparting to the effluent a roll-over motion in a channel under hydraulic pressure or by admission of compressed air. The channel is an annular duct with a vetical axis and the air is admitted close to the inner channel wall. Two concentric cylindrical guide walls assist the roll-over motion, one near the inner and the other near the outer wall of the annular channel. This sand trap is suitable for sewage plants covering 500-1000 people and requires very little space. It is inexpensive to build and requires very little power even if the rate of influent sewage fluctuates greatly. The sand can be discharged continuously.

Title: Electron charge write tube for reprography - controls gas discharge path outside tube for paper web electrostatic charging
Inventor: KIRSCHNER ERICH
IPC: G03G15/32
Filed: 1973-06-29
Abstract: The electrostatically charged paper is used as recording medium for indirect reproduction of half-tone images and documents, either directly according to an optical original, or an electric signal train corresponding to this original. A CRT for this reproduction has a window with numerous slits, made of a very thin metal foil of conductive material, instead of a luminescent screen. The foil thickness is only slightly greater than the penetration depth of the primary electrons of the electron beam. Thus on the output side appear slow secondary electrons but no primary electrons. The window is only 50-300 microns wide and the metal foil is vaulted over the narrow side outwards. The foil may be of A1 and its diffusion soldering may be Au plated.

Title: Carnot cycle heat producing engine - has heat exchangers and non absorptive sections
Inventor: GIGL RUDOLF
IPC: F25B29/00
Filed: 1974-03-07
Abstract: A Carnot cycle heat pump consists of an eccentric rotor and shell of alternating segments of poor heat conductor and good heat conductor. Two heat exchangers have shell segments as part of their walls. The gas filling is alternately adiabatically compressed and expanded in regions of poor heat conductor and isothermally expanded and compressed in regions of good heat conductor. In a lateral region, isothermal expansion, heat is removed from heat exchanger and in the opposite region isothermal compression heat is released to the heat exchanger to be transferred by pumps to heating systems etc. Sections of the shell have a corrugated form to reduce the overall length needed for good heat exchange.

Title: Fabrication of welding electrodes - by extruding a stack of sheet disks
Inventor: WALLBAUM HANS-JOACHIM DR RER N
IPC: B23K35/40
Filed: 1974-04-18
Abstract: Electrodes for resistance welding are fabricated from dispersion-hardenable materials which are rolled to form a sheet or strip.

Title: Wheelchair climbing stairs by endless tracks fore and aft with reversible electric motors driving left and right tracks separately
Inventor: RICHISON EUGENE MAYO
IPC: A61G5/06
Filed: 1974-04-23
Abstract: Two reversible electric motors one drive double-grooved wheels - independently, for steering - and thus the fore and aft endless tracks on each side of the vehicle. The tracks drive a pair of front wheels which, with a single central rear support wheel, provide the drive on level ground; they are held taut by idler wheels, and their slats, engaging the edges of a staircase, provide the drive up or down stairs. To climb a staircase: the chair is backed against the lowest step; a motor raises the rear wheel and tilts the chair back, triangular supports coming to rest against stops. The tracks now tilt to take the chair upstairs, the seat becoming horizontal. At the top the rear endless engages the landing first; when both are horizontal, the motor returns the seat and lowers the stern wheel ready to resume movement on the level.

Title: Quick acting air vent device - for pump in central heating installation, has low inertia spring adjusted float valve
Inventor: RICHTER WOLFGANG ING GRAD
IPC: F04D9/00
Filed: 1974-04-23
Abstract: The pump for the heating installation is provided with an air separating chamber on top of which the air vent arrangement is mounted, and consists of a cylindrical housing whic contains a ball float. The float is pressed down by a spring loaded lever against two strips which keep the ball clear from the water inlet opening. A small plate valve is mounted on the spring loaded lever. When the lever is pressed up by the ball float, the valve plate engages with a valve seat machined in the end of a tubular part mounted in the top of the air vent. When air escapes from the pump housing into the air vent, the water level in the air vent sinks, the float drops and the valve opens, assisted by the spring. While the air escapes, the water level rises again so that the float closes the valve.
